Severe pain.

Hey ladies ever since my first period ever I suffer from severe debilitating pelvic and lower back pain. I vomit and have diarrhea with every single cycle every month. No doctor takes me seriously and it's frustrating. I have tried different types of birth control but the side effects of them are so annoying and it doesn't ever take my pain away so it's pointless. Endometriosis had been tossed around before but I was told my symptoms don't match so i never got the surgery to confirm a diagnosis. Anyway, the point of this is to see if anyone else has this issue and what you all do for it? I've missed work and school over the years because I can't even get out of bed. Just curious to see and hear from others.
